“…By contrast, no significant difference in survival rates was detected among these three S. solea larval groups. In agreement with our results, Villalta [14] found that Senegal sole larvae fed with rotifers for the first 10 DAH and enriched with Artemia metanauplii from 6 to 30 DAH showed increased growth, in terms of individual dry weight and total length, particularly compared with larvae fed with rotifers alone. However, the authors reported no significant differences in survival rates among differently fed groups.…”

“…Villalta [14] showed the larvae of Senegal sole were able to capture enriched metanauplii after mouth opening without any differences in survival when compared with larvae that were fed with rotifers. When enriched metanauplii were present in sufficient quantity, larval development and growth appeared faster than in larvae fed with rotifers during the first 10 DAH.…”

“…However, Zhenhua [13] showed that prey density had a significant effect on the growth of pompano larvae. In a study by Villalta [14], two groups of Senegal sole (S. senegalensis) larvae were civilized: one had access to rotifers for the first 10 DAH as well as enriched Artemia metanauplii at 6-30 DAH, whereas the other group went without rotifers but had access to Artemia. The quantity of Artemia was the same (group A), twofold (group A2), or threefold (group A3) the quantity of live prey in the group fed with rotifers (group R).…”

In the present study, the most appropriate feeding regimes for the prevalent sole (Solea solea) larvae during the early larval rearing staged (first month) were investigated. Two experiments were conducted to improve the growth performance [the ultimate Body Weight (FBW), Specific Growth Rate (SGR), and Weight Gain (WG)] and survival rate of S. solea larvae. For each experiment, larvae were fed with alive rotifers and Artemia from the third and fifth Day After Hatching (DAH), respectively till the 30th DAH. In the first experiment, three feeding trials (10, 20, and 30 rotifers ml−1) were conducted (in triplicate for each treatment) to set the best rotifer densities as the first feed for S. solea larvae. In the second experiment, larvae were fed with Artemia at the 5 th (group Ӏ), 10 th (group ӀӀ), or 15 th (group ӀӀӀ) DAH (in triplicate for each treatment) to optimize the suitable timing for Artemia introduction to larval rearing tanks. The first experiment indicated that growth performance was enhanced by increasing the density of rotifers in the larval trials; larvae fed with 30 rotifers ml−1 showed the highest values for FBW (9.89±1.07mg), WG (8.89±1.07mg), and SGR% day−1 (8.44%±0.39%). Furthermore, standard length and survival rate increased significantly (p < 0.05) as rotifer density was increased to 30 rotifers ml−1, reaching 9.05 ±0.30mm and 85.99%±3.62%, respectively. The second experiment revealed that early introduction of Artemia at the 5th DAH in larval tanks led to a significant (p<0.05) rise in FBW, WG, and SGR% day-1 in S. solea larvae (10.18±0.88mg, 9.18±0.87mg, and 8.57%±0.33%, respectively). Additionally, the survival rate of larvae was improved slightly in group Ӏ compared with the survival rates in groups ӀӀ and ӀӀӀ. Findings of this work concluded that feeding a high density of rotifers to S. solea larvae significantly increased the survival rate, standard length, and width of the larvae. Additionally, introducing Artemia in the early stage after hatching rather than later significantly increased S. solea larval growth rate, survival, stander length, and width.
